Current text · last reform published in the Official Gazette of the Federation (DOF) on 14 May 2026
The prescription is interrupted:
I.By the mere presentation of the claim or of any motion before the court, independently of the date of the notification. If the person promoting omitted to exhaust the conciliation procedure not being exempted from doing so, the court, without fixing competence over the matter, shall remit it to the competent Conciliating Authority so that it initiates the conciliation procedure established in Title Thirteen Bis of this Law. It is not an obstacle for the interruption that the court be incompetent;
II.If the person in whose favor the prescription runs recognizes the right of the one against whom the prescription runs, by word, in writing or by undeniable facts.
III.By the presentation of the conciliation request referred to in article 684-B of this Law. The interruption of the prescription shall cease from the day following that on which the Conciliation Center issues the certificate of non-conciliation or, where appropriate, the archiving of the file is determined for lack of interest of a party. It is not an obstacle for the interruption that the Conciliating Authority before which it was promoted be incompetent.
